Add Sherpa_i updates from 21.6 branch.
Both 21.6 and master should now be in sync with this commit.
The changes were tested with
cd Generators/Sherpa_i/share/example/simple
Gen_tf.py --ecmEnergy=13000.0 --maxEvents=1 --jobConfig=. --outputEVNTFile=tmp.pool.root
./makelibs
Gen_tf.py --ecmEnergy=13000.0 --maxEvents=1 --jobConfig=. --outputEVNTFile=tmp.pool.root
which works fine.
